`will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this spec1ncation,l 1n

Iigure 1 is aside elevational view, partly in vertical section, of a tank-car constructed 1n accordance with my invention. big. 2 is a cross-sectional view taken on the line 2 2 of 141g. 41. Iig. 3 is an end elevational view with the upper portion ofthe tank broken away. Fig. 4 is alsectional view taken on the line 4 4 of Fig. 1; and Fig. 5 is a view similar to Fig. 2, illustrating a modified form. This invention relates to new and .useful improvements in tank-cars, the object being to provldel a car possessing 'maximum strength and minimum weight. In a tankcar the Weight of the tank and its contents act as a load which tends to place the bottom of the tank structure in tension and the top of said structure in compression. In accordance With my invention this load is supported by longitudinal braces arranged'above the center of the tank and a longitudinal sill secured to the bottom ofthe tank. The uper portion of this longitudinal sill is located lnside of the tank, and its lower portion extends below the tank. The longitudinal sill in addition to reinforcing the tank structure is arranged to receive the buflng and pulling stresses and transmit said stresses i om end to end of the carin a straight line. Referring to the drawings, the tank is provided with a suitable lilllng-dome 1 and a discharge-valve 2.

3 indicates a`runn1ng-board, and 4 is a hand-rail -supported by brackets 4", secured to the longitudinal flanges of the tank. Flanged heads 5 close the ends of the tank.

' A curved sheet 6 forms the top of the tank,

and the side and bottom walls of `said tank are also formed by curved sheets 7. The sheets 6 and 7 referably extend from end to en'd of the taillis) and are riveted to the heads 5. The adjacent edges of the sheets 7 and 6 are flanged outwardly, and tank-braces 8 are interposed between andriveted to the flanges. These braces extend beyond said anges in one or both directions, said braces preferably extending into the tank. The lower edges of the sheets 7 are fl'anged outwardly, the flanges being arranged on opposite sides of the vertical web ofa longitudinal sill. hivets 9 secure said web and fianges together. l The longitudinal sill is preferably vI-shaped 1n cross-section and may be a rolled I-beam or a built-up structure com- A prising a web plate 10, reinforced by angles 11 and 12 at its longitudinal edges. lhe upper portion of this silllis preferably a'rranged inside of the tank, and its lowerportion preferably extends' below the tank.

Short draft-sills are located under and project beyond the ends of the tank. The top portions 13 of the draft-sills are preferably riveted to the tank and provided with flanges 14, which are riveted to the lower flanges of the tank-sheets 7. Draft-lugs 15, between which any suitable draft-rigglng maybe a plied, are secured to vertical Webs 16 of t e draft-sills. Buffer-blocks 17 cover the outer ends of the-draft-sills, the inner ends of said sills preferably extending through body-bolsters, which are located near the ends of the tank. The body-holsters are connectedby the longitudinal sill ,which passes through the cent-er of said bolsters. Each body-bolster contains central filler-blocks 18,-` which are riveted to the longitudinal sill. These blocks are arranged betweensaid sill and the vertical webs 16 of the draft-sills.

19 indicates center bearings, which are secured to the body-holsters below the fillerblocks 18.

20 indicates side wings of the bolsters, the

upper portions of which are curved and riveted to the tank, the inner faces of said wings being riveted to the filler-blocks 18, the rivets also passing through the vertical Webs of the draft-sills.

My invention is not limited to body-bolsters and draft-sills constructed as herein shown and described', as many different designs of bolsters and draft members may be employed in connection with this invention.

Fig. 5 illustrates a tank composed of four longitudinal sheets. Tank-braces 6a and 7a extend into lthe tank and are interposed between the adjacent edges of the longitudinal tank-sheets. If desired, these braces .may

.girder arranged partially lextend outside of the tank, as shown by dotted mes.

21 indicates an internal sill which is riveted to the bottom tank-sheet.

22 and 23 indicate the body-bolsters and draft-sills, respectively.

The tank shown in Fig. 6 could be used with the ordinary underf'rame, or by modifying the bottom tank-sheet the longitudinal sill shown in Figs.. 1 '.l and 2 could be appliedto this tank. y 1 Y' I am aware that'minor changes in the construction, arrangement, and combination of the various parts 'of my device could be made and substituted for-those herein shown and described without departing, from thenature and principle ofmy invention.
